摘　　要：针对安徽沿淮地区气候特点,通过试验筛选出适宜沿淮地区旱种旱管栽培,丰产性和稳产性较好的旱稻品种5个,节水耐旱型水稻品种7个;明确了沿淮地区以旱优73为代表的杂交旱稻的丰产节水栽培技术:播种期6月5-12日,播种量2.0 kg/667 m^2左右,氮肥用量10~14 kg/667 m^2;在施肥过程中适当降低基蘖肥用量、增施穗粒肥,基、蘖、穗肥比例以4∶4∶2较好。In order to clarify the key techniques of high-yielding and water-saving cultivations of upland hybrid rice, the field experiments were carried out in the regions along the Huaihe River. 5 upland rice varieties with high and stable yield, and 7 lowland rice varieties with water-saving and drought resistant traits were selected. Further, the key techniques of high-yielding and water-saving cultivations of upland hybrid rice Hanyou 73 were determined in the regions along the Huaihe River： the suitable seeding date ranged from June 5th to 12th, the optimum seeding rate was 2.0 kg/667 m2, the recommended application rate for nitrogen fertilizer was 10~14 kg/667 m2 and 40% nitrogen fertilizer as basal fertilizer, 40% nitrogen fertilizer as tillering fertilizer and 20% nitrogen fertilizer as earing fertilizer.
